Outdoor stone relics, including inscriptions, statues, temple grottoes, etc., are continuously subjected to natural weathering and air pollutants. Those made of marbles other carbonate rocks particularly vulnerable acid rains, which can be protected by acid-resistant coatings. A novel method prepare enamel-like hydroxyapatite coating on marble surfaces is presented in this paper analyzed using optical microscopy, a scanning electronic microscope, grazing incident X-ray diffraction,...
Abstract Nanhai I is a highly valuable shipwreck of the Southern Song Dynasty for studying various topics, including shipbuilding techniques. The sealing materials are significant importance to ensure ship’s reliability during voyage across ocean and they were rarely analyzed. Therefore, this ship analyzed by several analytical approaches. included two types, i.e., gap filler with jute fibers surface coating without any oakum. main components both types putty calcite minor Tung oil. weight...
Abstract Glass beads excavated from Nanhai I shipwreck were investigated with scanning electron microscopy energy dispersive spectrometer (SEM–EDS), Raman spectroscopy, multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) and X-ray diffraction (XRD). Dating back to the Southern Song Dynasty, these help study Chinese maritime trades during twelfth–thirteenth century. The bead samples are categorized into five groups by color, i.e., yellow, orange-red, blue, dark red light...
Dehydration is the principal conservation process for waterlogged archaeological wood (WAW), with aim of preventing shrinkage and cracking. For well-preserved WAW, mainly takes place when moisture content below fiber saturation point. Here, we conduct a new trial using ionic liquid as dimensional stabilizer to maintain stable swollen state WAW. Molecular dynamics simulation (MD), measurement, Fourier transform infrared spectroscopy (FTIR), dynamic vapor sorption (DVS) were adopted...
